Diode flash info:
- green with frequency about 1 Hz (1 per second) - phone is network area.
- 2 fast flashes of diode during standby mode means that the phone changes channel.
- green flashing with high frequency. Means that you have unread SMS message or a phone call.
- flashing red - weak battery.
- red diode on - battery charge
- green diode on - phone's battery is full and battery charger is connected. 
Activate net monitor: (pause means * holded until you see square)
